7 Claims. (Cl. 93-2) The present invention relates to a method of wrapping packages, and has special reference to a method of wrapping packages of hard or cooked candies in which the candies are arranged in stacks or rolls.

Rolls of hard or cooked candies are commonly wrapped first with a waxed paper wrapper which is wound around the periphery of the roll and its ends tucked in over the ends of the roll, and then similarly wrapped with a sheet of foil, the foil enclosing the waxed paper. Heat is then applied to the tucked in ends and peripheral surface of the foil. wrapper so as to partially melt the wax of the waxed paper wrapper which when allowed to cool tightly seals the longitudinal seam and the end tucks of the wrappers. Owing to such heat-sealing of the wrappers it is difiicult to open the package which is usually done by attempting to open up the tucks of the two wrappers at one end of the package with the will be readily understood from the following description and accompanying drawings, in

which:

Figure 1 is a plan view ofa portion of a composite paper strip of wrapping material and tearing ribbon previously to being cut to form the individual wrappers in accordance with my improved method;

The present application is a division of my pending application Ser. No. 283,200, filed July 7, 1939, the latter application being a division of application Ser. No. 135,655, filed April 8, 1937, which has issued into patent No. 2,189,347, dated February 6, 1940.

In wrapping a stack or roll of articles 2 (Fig. 3) such as hard candies that are in the form of circular disks, a strip of waxed paper 4 and a strip of unwaxed paper or glasslne 6 are placed one above the other, the glassine being narrower and spaced equal distances from the longitudinal edges of the waxed strip 4. The composite strip thus provided is cut on lines 8 to form the individual wrappers as illustrated in Fig. 2. This composite wrapper is initially applied to the candy roll by wrapping it about the peripheral surface of the roll with the unwaxed paper on the insideas illustrated in Figs. 3 and 4. When the composite wrapper is thus applied the glassine lining extends slightly beyond the ends of the candy roll and the waxed paper extends a distance beyond the lining. Thereafter the ends of the two wrappers are tucked in over the ends of the roll, the tucks ll) of the waxed paper-wrapperbeing radially arranged in overlapping relation.

The package with the paper wrapping applied is then similarly wrapped in foil I 2 (Fig. 6), the end tucks I4 of the foil wrapper being arranged similarly to the paper tucks l0. Thereafter heat is applied to the tucked in ends and peripheral surface of the foil wrapper so as to partially melt the wax of the Waxed paper wrapper and seal the package, the radial end tucks of the paper wrapper being firmly secured together. After this heat-sealing operper strips. This tearing strip may be of textile material and in the form of a narrow ribbon.

' oi the waxed paper, and are firmly pressed together so as to secure the tearing ribbon 18 between them when the wax becomes cool. The tearing ribbon i8 is cut oil! upon cutting the paper strips 4 and 8 upon the lines 8 to form the individual wrappers. The tearing ribbon is applied and cut off in such a manner that in the individual wrappers the inner curved portion 20 of the tearing ribbon extends in an arc from substantially one of the inner corners 22 oi! the glassine lining to substantially the center of the wrapper, with the remaining portion of the tearing strip projecting out from beneath the unwaxed paper with its end portion projecting beyond the waxed paper as shown.

In wrapping the composite paper wrapper about the roll of candles, when the wrapper has been wrapped substantially once around the roll as illustrated in Fig. 3, the inner end portion or the tearing ribbon is crossed by the outer portion or the ribbon, and during the balance of the winding of the wrappers about the roll, the outer end of the ribbon is held outwardly so that when the wrapper is completely wrapped about the roll the outer end of the ribbon will project from the open end.

During the tucking in of the ends of the wrapper, the outer end of the tearingribbon is continued to be held outwardly from the package. At the completion of the tucking operation, the outer end or the tearing ribbon projects outwardly from between the two plies of the last tuck to be formed.

The outer end or the tearing ribbon is also held outwardly during the wrapping of the package in foil, and at the completion of the tucking in of the ends of the foil the end of the tearing strip projects outwardly from beneath the end .01 the last tuck that is formed. The excess amount or the ribbon may then be cut of! by means of cutting knives 24.

With the tearing strip thus applied, upon pulling outwardly on the outer end or the ribbon, the outer ply of the outermost tuck or the ribbon end of the package is first torn down to the' periphery of said end. Then upon continued pulling on the tearing ribbon, the ribbon tears the wrappers, both the toil and paper wrapper, about said edge of said end as illustrated in Figs. 8 and 9 so as to completely sever off this end of the wrapper exposing the endmost candies.

During this tearing operation, the looped arrangement of the tearing ribbon about the peripheral surface of the package and the tact that itis secured by the wax of the wrappers, causes the ribbon to naturally tear around the edge or the package and this may be done without opening up the wax sealed tucks.

'Instead of pulling straight out from the end of the package, if the tearing ribbon is pulled downwardl it may be caused to follow its loop arrangement around the package, thus causing several candies to be exposed to view.

In the package and method illustrated in Figs. 10 to 19, inclusive, the tearing ribbon may be ap- 'plied to the two strips similarly to that above described as shown in Fig. 10. In cutting the composite strip to form the individual packages, the strips are cut on lines 28 which causes the inner end portion oi. the tearing ribbon to project from the wrappers a greater distance thanthe outer end portion.

When the paper wrapping is applied to the peripheral surface or the candy roll, instead 0! the outer end of the tearing ribbon projecting from the end or the package, the inner end pro- .iects from the end or the package, the inner end portion oi! the ribbon extending across the underside oi the outer end portion. Upon pulling on the end or the ribbon as thus applied, the end tucks are successively opened up as the strip travels about the package. In this form the end tucks may be opened up without substantial tearing or the wrapping.

Where no glassine lining is employed, the tearing ribbon may be secured to the waxed paper wrapper alone.

As will be evident to those skilled in the art, my invention permits various modifications without departing from the spirit thereof or the scope or the appended claims.

What I claim is:

1. The method of wrapping an article of cylindrical form which comprises arranging a waxed paper strip and an unwaxed paper strip one upon the other, the unwaxed paper strip being narrower and having its longitudinal edges spaced from the longitudinal edges of the waxed paper strip, applying a tearing strip in a sinuous line made up or oppositely directed curves alternately arranged with corresponding curved portions thereof positioned between the paper strips and the remaining portions of the tearing strip pro- Jecting beyond one edge of the unwaxed paper strip, applying heat to the two paper strips so as to melt the wax on the inner side or the waxed paper strip. firmly pressing the two strips together, allowing the wax to cool so as to secure the tearing strip in position between the two paper strips, cutting the composite paper strips and tearing strip thus formed transversely so as to form individual wrappers, each wrapper having a tearing strip having a curved portion extending between the two paper sheets and the ends thereof projecting beyond one longitudinal edge of the unwaxed paper sheet, the portion of.

the tearing strip between said sheets extending substantially one half the length of the composite sheet, wrapping each individual composite wrapper approximately twice around the peripheral surface of the article, and tucking in the ends of the wrapper over the ends of the article with one end of the tearing strip projecting out from one of the tucked in ends or the wrapper.

2. The method of wrapping an article which comprises detachably securing a tearing strip to one side or a wrapper for the article, the tearing strip being arranged in a curve having at least one end projecting from one of the longitudinal edges of the wrapper, winding the wrapper about --the article with the tearing strip on the inside,

and tucking in the ends oi the wrapper over the ends of the article, whereby the tearing strip is I looped about the article with one of its ends prothe longitudinal edges or the unwaxed paper spaced inwardly from the longitudinal edges of the waxed paper, positioning a tearing strip on the inner side of the waxed paper with a portion of th strip arranged in a curve between the waxed paper and the unwaxed paper and with at least one of the ends of the strip projecting beyond one of the longitudinal edges of the waxed paper, winding the composite wrapper about the article with the unwaxed paper on the inside so as to cause the tearing strip to be looped around the article, and tucking in the ends of the wrapper over the ends 0'! the article with one end of the strip projecting out from one of the tucked in ends of the wrapper.

4. The method of wrapping an article which comprises detachably securing a tearing strip to one side of a wrapper for the article with one end of the tearing strip arranged adjacent one of the longitudinal edges of the wrapper and its other end projecting outwardly beyond said longitudinal edge, a portion of the tearing strip between its ends being bent a distance inwardly from said longitudinal edge, winding the wrapper about the article with the tearing strip on the inside, and

tucking in the ends of the wrapper over the ends of the article whereby the tearing strip is looped about the article with said projecting end of the tearing strip projecting outwardly from beneath the wrapper tucks at one end of the article.

5. The method of forming a wrapper for an article of cylindrical form which comprises arranging a waxed paper strip and an unwaxed paper strip one upon the other, the unwaxed paper strip being narrower and having its longitudinal edges spaced from the longitudinal edges of the waxed paper strip, applying a tearing strip in a sinuous line made up of oppositely directed curves alternately arranged with corresponding curved portions thereof positioned between the paper strips and the remaining portions of the tearing strip projecting beyond one edge of the unwaxed paper strip, applying heat to the two paper strips so as to melt the wax on 'the inner side of the waxed paper strip, firmly pressing the two strips together, allowing the wax to cool so as to secure the tearing strip in position between the two paper strips, cutting the composite paper strips and tearing strip thus formed transversely so as to form individual wrappers, each wrapper having a tearing strip having a curved portion extending between the two paper sheets and the ends thereof projecting beyond one 1ongitudinal edge of the unwaxed paper sheet, the portion of the tearing strip between said sheets extending substantially one half the length of the composite sheet.

6. The method of forming a wrapper for an article which comprises arranging a sheet of waxed paper and a sheet of unwaxed paper one upon the other with the longitudinal edges of the unwaxed paper spaced inwardly from the longitudinal edges of the waxed paper, and positioning a tearing strip on the inner side of the waxed paper with a portion or the strip arranged in a curve between the waxed paper and the unwaxed paper and with at least one of the ends of the strip projecting beyond one of the longitudinal edges of the waxed paper.

7. The method of forming a wrapper for an article which comprises forming a rectangular sheet of wrapping material, and detachably securing a tearing strip to one side of said sheet with one end of the tearing strip arranged adjacent one of the longitudinal edges of the wrapper and its other end projecting outwardly beyond said longitudinal edge, a portion of the tearing strip between its ends being bent a distance inwardly from said longitudinal edge.
